From the top of my head I thought about some of things that shouldn't be difficult to integrate yet add to its usability:
-Zoom on extents! Kind of annoying to have to scroll and move around to find that new imported OBJ :/
-When you jump from a node that has a part of its "tree" collapsed to another node and then jump back, the tree is extended again. Kind of annoying if you're already finished editing a series of materials and you have to scroll back again to find the next one you were gonna edit.
-Ability to merge imported objects on the same scene. Nothing fancy, just display both scenes simultaneously. Example: a generic scene to show of a car, and the ability to place a different car into it. Unlink first car, link the second, presto.
-Blurred refractions for a spec material
-Ability to pan around the graph editor, for increased real state
-Falloff map
Thanks for this fantastic SW
